std::shared_lock::release - std::shared_lock::release
mutex_type* release() noexcept; (since C++14)
Breaks the association of the associated mutex, if any, and *this.
No locks are unlocked. If the *this held ownership of the associated mutex
prior to
the call, the caller is now responsible to unlock the mutex.
Pointer to the associated mutex or a null pointer if there was no
associated mutex.

Reason: no example
unlock unlocks the associated mutex
(public member function)
disassociates the associated mutex without unlocking (i.e., releasing
release ownership of) it
(public member function of std::unique_lock<Mutex>)
